[Bug ipa/61548] [5 Regression] FAIL: gcc.dg/tls/alias-1.c (internal compiler error)

Proposed fix

Ok, there seems to be 3 issues ;)  First is that emutls does not resolve alias
after introducing it.  Second is that we may end up removing alias target
before alias in ipa.c and third is that vaprool_node::remove actually removes
the reference before attempting to use it.

I would welcome if someone tests this on one of the targets reproducing the
problem
